Moscow's Age Relative to St. Petersburg

Moscow is approximately 210 years older than St. Petersburg.

This age difference can be attributed to the founding dates of the two cities. Moscow was established around the 12th century, while St. Petersburg was founded in 1703 by Peter the Great This makes Moscow significantly older than St. Petersburg by several centuries.
